Xcode 6无法找到模拟器设备并超时

Question

我已经提交了雷达,因为我认为这是一个错误,但我想知道是否有人可以在此期间建议解决方案.

在安装了Xcode的计算机上成功运行数周后,测试将不再执行.似乎Xcode无法再找到模拟器或其设备.从Xcode中的Devices菜单(以及所有目录中~/Library/Developer/CoreSimulator/Devices)删除模拟器设备并再次添加它们无济于事.

模拟器不会启动,并且Xcode中不会输出任何错误消息.system.log在Console.app中打开会显示以下消息:

删除〜/ Library/Developer/CoreSimulator/Devices中的设备是不可取的,因为您可能正在运行时从CoreSimulatorService下删除状态.我建议你通过以下方式"清理":

1. 使用sim退出Xcode,iOS模拟器,乐器和其他任何东西
2. 杀死服务: killall -9 com.apple.CoreSimulator.CoreSimulatorService
3. 删除状态: rm -rf ~/Library/*/CoreSimulator

这应该会让你回到一个香草州.

如果这不能完全解决您的问题,请在重现问题后使用〜/ Library/Logs/CoreSimulator/CoreSimulator.log更新您的问题.请注意,您应首先启用调试日志记录:

defaults write com.apple.iphonesimulator DebugLogging -bool YES
defaults write com.apple.CoreSimulator DebugLogging -bool YES
